This invention relates to transferring; V mechanism -forfilling replenishing looms and is more particularlydirected to the means ion holding-the tip end; portion of thebobbin orfilling carrieras it is trans ferred from; the hopper to; the shuttle;

When a filling carrier; or; bobbin to be ejected: from the shuttleandanew one substituted, the incomingfilling carrier or bob- 10 and eii ectiveameans for engaging-and hold;- ing the tip of a bobbin to prevent nnsplacement of the bobbin: during transfer'to, the

Inaccord-ance with the present; invention,

the usual rtrans ferrer isavpro ided with a bobbin tip: head on; which are pivotally mounted at each side of its: center, bobbintipengaging jaws having tail portions,;be-

So fan'asthe present invention 18 con-- cerned, the tip support 15 may or may not be employed.

Secured to and extending laterally from the head 16 of the transferrer 8 is the rod 17 which in the present instance is shown as secured to the transferrer by means of a set screw 18. The rod 17 extends in substantial parallelism with the axes of the bobbins or filling carriers in the hopper, and at its outer end is provided with means for gripping and holding the end of the filling carrierduring transfer. The supporting element for the parts to be hereinafter described may be conveniently designated as the bobbin tip head, and comprises the hub portion 19 to which is secured the plate 20, and these parts may be connected to the rod 17 by a proper securing device, such as the set screw 21.

Pivotally mounted on the bobbin tip head, one at each side of the center of such head, are the bobbin engaging jaws 22 and 23. The pivotal connection of the two jaws to the head may be variously contrived, but is herein shown as formed of the pins 2%, one for each jaw, located at opposite sides of the substantially vertical longitudinal center of the bobbin tip head, as indicated in Figs. 3 and 4.

Each of the bobbin holding jaws 22 and 23 is thus pivotally mounted upon the head and is provided with a bobbin engaging portion 25 below the pivotal mountings, and with tail portions 26 extending upwardly from the pivotal supports 23 and Mounted on the head for movement reiative to the jaws and to effect their opening and closing movements is a jaw closer 27, the upper stem portion of which is mounted for sliding movement in a guideway formed by a lu 28 secured to the head.

The jaw closer, more specifically described herein, has a wedge portion 29, which cooperates with complementai inclined surfaces 30 on the tail portions 26 of the jaws, the construction being such that movement of the jaw closer upwardly will cause the wedge 29 to act upon the tail portions of the jaws and close the jaw engaging portions of the jaws about the bobbin tip located between the jaws, and conversely, movement of the jaw closer in the opposite direction is utilized in effecting an opening movement of the jaw engaging portion of the jaws.

The jaw closer has a stem 31 extending downwardly between the jaws from the wedge portion 29 of the jaw closer, and between the upper end of the stem and the guiding recess formed in the block 28 is a spring 32 normally acting lightly upon the jaw closer to move it downwardly into the position indicated in Fig. 4, which is the jaw open position.

The tail portions 26 of the jaws are normally under the influence of spring means tending to move the tail portions towards each other, and perforce cause the bobbin engaging portion of the jaws to open. In the present instance of the invention the head 20 has extending therefrom a pin 33 about which is wound the coils "A of a spring, the two arms 35 of which rest upon the tail portions 26 of the jaws above their pivotal supports, as indicated in Figs. 3 and 4, the result being that the action of the spring upon the tail portion of the jaws is to open the jaws when the jaw closer is moved downwardly by its spring Inasmuch as the features constituting the present invention are subject to the accumulation of lint during weaving, which may obstruct their free action, the present invention further contemplates a cover plate 36 which may extend over the head 20, as indicated in Figs. 2 and 3, and may enclose the movable parts included by the present invention. The cover plate 3b is provided with side flange portions 37 which overlie the edge portions of the head 20, and the cover plate is conveniently secured to the head by the screws 38, as indicated in Fig. -l, and the lower portion of the cover plate may be further secured to the head by means of the threaded end portions of the pivotal studs 2% on which the jaws are mounted. In this latter case, the ends of the pivots 2i would be passed through holes 39 of the cover plate and their outer ends be provided with suitable nuts 40.

ffhen a bobbin is to be transferred to the shuttle, the transferrer is moved downwardly and the head 16 of the transferrer engages the head of the bobbin, while the tip end portion of the bobbin is first enclosed by the open jaw portions 25 of the jaws and then the extension 31 of the jaw closer contacts with the bobbin tip and is moved upwardly, thereby causing the wedge 25) of the jaw closer to positively close the jaws about the tip of the bobbin. -When the bobbin has been placed in the shuttle by the transferi-(n' and the transferrer starts ujnvardly to its inoperative position, the spring 32 acting upon the jaw closer moves the jaw closer downwardly, thereby permitting the spring arms 35 to move the tail portions of the jaw towards each other and the wedge 29 of the jaw closer descends, so that as soon as pres sure is taken off the jaw closer, the jaw is opened by virtue of the spring 32 acting to return the jaw closer to its jaw open position.

What is claimed is:

1. In a filling replenishing loom, the combination of a hopper for filling carriers, a transferrer having an arm extending therefrom in substantially parallel relation to the bobbin to be transferred. a head fixed to said aim and having pivoted jaws to engage the up of a bobbin to be transferred actuated by downward movement of the transferrer, a

jaw closing slide having upwardly convergjaws and close bothjaws about the tip of a bobbin, and a spring for returning the jaw closing slide into normal position to permit both jaws to release the bobbin as the transtl'errer starts upwardly.

2. In a filling replenishing loom, the com bination of a transferrer having spring separated pivoted jaws both of which are pivot" ally mounted to engage and hold the tip of a iilling carrier during transfer, tail portions extending upwardly from the pivots of the jaws, a jaw closer having wedge portion mounted for sliding movement between the tails of the aws, and a spring normally tendi'ug to depress the jaw closer wedge to permit the spring separated jaws to open for the reception of the tip of the filling carrier but yieldable on transfer movement of the trans ferrer by engagement with the filling'carrier to permit the two jaws to be positively closed by movement of the jaw closer wedge.

In a filling replenishing loom, the combination of a transferrer having two pivoted jaws to engage and hold the tip of a filling carrier, a head on which the aws are pivoted at opposite sides of the ver ical center line of the head, a spring acting upon the two pivoted jaws above their pivots to separate the jaws, a jaw closer mounted on the head for sliding movement between the two pivoted jaws and having a double incline or wedge converging upwardly to cause closing movement of the jaws as the jaw closer meets the tip of a filling carrier during the operation of the transferrer, and a spring for moving the jaw closer downwardly to 1 ermit the jaw opening spring to open both jaws as the transferrer starts upwardly to inoperative position. I
